Modeling fertility curves in Africa [PDF]

open access: yes
The modeling of fertility patterns is an essential method researchers use to understand world-wide population patterns. Various types of fertility models have been reported in the literature to capture the patterns specific to developed countries.

Stage‐Specific H3K14 and H3K23 Succinylation Orchestrates Insect Metamorphosis and Oogenesis

open access: yesAdvanced Science, EarlyView.
Stage‐specific succinylation of histone H3 at lysine 14 and 23 differentially controls insect metamorphosis and oogenesis through distinct GPCR‐PKC signaling cascades, revealing an evolutionarily conserved epigenetic mechanism that coordinates key life‐history traits.

Population Policies, Fertility, Women's Human Capital, and Child Quality [PDF]

open access: yes
Population policies are defined here as voluntary programs which help people control their fertility and expect to improve their lives. There are few studies of the long-run effects of policy-induced changes in fertility on the welfare of women, such as ...

Apartheid's children: Social institutions and birth intervals during the South African fertility decline, 1960-1998 [PDF]

open access: yes
Previous research on the demography of South Africa has not resolved whether the South African fertility decline should be viewed as rapid given the institutional forces ranged against the everyday lives of African South Africans, or as slow, given the ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

open access: yesAdvanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Unconventional Hysteretic Charge Filling in Moiré‐Reconstructed Helical Trilayer Graphene

open access: yesAdvanced Science, EarlyView.
In helical trilayer graphene, sequential twisting reconstructs the moiré landscape into periodic domains separated by aperiodic boundaries. Longitudinal transport reveals sweep‐direction‐dependent hysteresis, while the Hall response traces this behavior to hysteretic charge filling at the aperiodic boundaries.
